From 1989 until his death in 2007, Horst Ademeit documented the presence of “cold rays”--unseen negative forces permeating everyday objects--in thousands of Polaroids and digital photographs, as well as notebooks full of meticulously logged data. Secret Universe shows images of the “cold rays” at work, in enigmatic images of street scenes, grocery items and bizarre measuring instruments.
